ESTIMATE CONFIDENCE—
Gaming Engine v2 combines benchmark-calibrated CPU/GPU pairing indices with the selected GPU's native 1080p, 1440p, and 4K raster scaling. A calibrated nonlinear curve improves mild GPU-limited estimates without inflating severe mismatches, while the dead zone filters benchmark noise. The result remains a comparative estimate rather than a universal per-game utilization measurement.
This is a comparative estimate, not a direct benchmark of your individual PC. Games, settings, drivers, cooling, and background software can change real-world performance.
WHY IT MATTERS
A Balanced PC Gives You More From Your Hardware
A bottleneck happens when one component cannot keep up with another, limiting the performance your system can deliver.
CPU Bottleneck
Your processor may struggle to prepare frames or handle game logic quickly enough for the graphics card.
GPU Bottleneck
Your graphics card may be the limiting component, especially at higher resolutions and demanding visual settings.
Balanced Build
A well-balanced system allows both major components to work efficiently without a significant mismatch.
HOW IT WORKS
Simple Inputs. Clear Results.
Our calculator will compare the relative performance of your CPU and GPU while considering resolution and the type of work you want your PC to perform.

COMMON QUESTIONS
Frequently Asked Questions
What is a CPU and GPU bottleneck?
A bottleneck occurs when one component limits how much performance another component can deliver. In many games, the CPU and GPU can become the limiting component under different conditions.
Is a small bottleneck bad?
Not necessarily. Every computer has a limiting component at some point. Small differences between CPU and GPU performance are normal.
Does resolution affect bottlenecks?
Yes. Lower resolutions can place more emphasis on CPU performance, while higher resolutions usually increase the workload placed on the graphics card.
Are bottleneck percentages exact?
No. They are estimates. Actual performance can change between games, applications, settings, drivers, cooling, and other hardware.
